[0025] like Figure 2 to Figure 4 As shown, an R-knife fixing device of the utility model comprises a knife seat 1, wherein the knife seat 1 comprises a mounting seat 11 and a fixing seat 12 for being installed on a slitting machine, wherein a locking structure is arranged on the knife seat 1, wherein the mounting seat 11 and the fixing seat 12 are connected via the locking structure, and an installation groove 13 is provided on the knife seat 1, wherein the installation groove 13 comprises a positioning groove 131 and an adjusting groove 132 which are relatively arranged, wherein the positioning groove 131 is located on the mounting seat 11, and the adjusting groove 132 is located on the fixing seat 12.

[0026] When installing the R knife, place the handle of the R knife in the installation groove 13, and drive the fixing seat 12 to move toward the installation seat 11 through the locking structure, so that the positioning groove 131 and the adjusting groove 132 surround the R knife, adjust the position of the R knife, and then lock and fix it through the locking structure. When fixed, the R knife is in surface contact with the installation groove 13 composed of the adjusting groove 132 and the positioning groove 131, so the contact area is large, the static friction is large, and the fixing effect is good.

[0027] In this embodiment, the fixing seat 12 and the mounting seat 11 are arranged separately, so as to facilitate the clamping of the R knife.

[0028] In other embodiments of the present application, the fixed seat 12 and the mounting seat 11 can also be an integrated structure. In this case, a clamping groove is opened on the tool seat 1, and the clamping groove passes through the mounting groove 13. The locking structure drives the fixed seat 12 to deform toward the mounting seat 11, the width of the clamping groove is reduced, and the mounting groove 13 is deformed to hold the R tool.

[0029] In this embodiment, the locking structure includes a fixing screw 2, and an adjustment hole is opened on the knife seat 1. The adjustment hole includes a positioning hole 121 located on the fixing seat 12 and a threaded hole 111 located on the mounting seat 11. The fixing screw 2 passes through the positioning hole 121 and is fixedly installed in the threaded hole 111.

[0030] Rotating the fixing screw 2 drives the fixing seat 12 to move toward the mounting seat 11, and the positioning groove 131 and the adjusting groove 132 embrace the R knife tightly, with a simple structure and strong practicality.

[0031] In this embodiment, the fixing screws 2 are arranged in an even number, and the even number of fixing screws are symmetrically arranged on both sides of the axis of the installation slot 13. By symmetrically arranging the fixing screws 2 on both sides of the installation slot 13, the forces on both sides of the installation slot 13 are uniform. Preferably, two fixing screws 2 are arranged, so that the R knife can adjust the installation depth in the installation slot 13 conveniently, with simple structure, low cost and strong practicality.

[0032] It can be understood that in other embodiments of the present application, when the fixed seat 12 and the mounting seat 11 are separated, the locking structure can also be a first rack and a second rack that cooperate with each other, and the first rack and the second rack are both set to two, respectively set on both sides of the axis of the mounting groove 13, the first rack is fixed to the fixed seat 12, and the second rack is set in a locking groove opened on the mounting seat 11, and can move along the length direction perpendicular to the first rack. The back of the second rack is provided with a compression spring before the mounting seat 11, and one end of the second rack extends out of the mounting seat 11. After setting the installation position of the R knife, the fixed seat 12 is directly squeezed toward the mounting seat 11, and the first rack is inserted into the locking groove to squeeze the second rack. When the R knife is held tightly, stop squeezing the fixed seat 12, and the second rack is clamped and fixed between the first rack under the action of the spring. When the position of the R knife needs to be adjusted or replaced, it is only necessary to move the end of the second rack extending out of the mounting seat 11 to squeeze the spring and release the first rack.

[0033] In other embodiments of the present application, a guide block may be fixedly connected to the handle of the R-knife, and a guide groove cooperating with the guide block is provided along the length direction of the positioning groove 131. Limiting the circumferential rotation of the R-knife is beneficial to reducing the displacement of the R-knife and improving production quality.

[0034] In other embodiments of the present application, an elastic gasket is provided in the positioning groove 131, which plays a buffering role to avoid damage to the R-knife caused by over-tightening when tightening the fixing screw 2. The structure is simple and practical.

[0035] The principle of the present application is as follows: the handle of the R knife is placed in the installation groove 13, and the fixing screw 2 is installed on the installation seat 11 through the adjustment hole on the fixing seat 12, so that the positioning groove 131 and the adjustment groove 132 surround the R knife. Adjust the position of the R knife, tighten the fixing screws 2 on both sides of the installation groove 13 respectively, and the fixing seat 12 cooperates with the installation seat 11 to hold and fix the R knife. When fixed, the R knife and the installation groove 13 composed of the adjustment groove 132 and the positioning groove 131 are in surface contact, with a large contact area, large static friction, and a good fixing effect.

[0036] The above is a detailed introduction to an R-knife fixing device provided by the utility model. The description of the specific embodiment is only used to help understand the method and core idea of ​​the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, several improvements and modifications can be made to the utility model, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
